AUS Blackwood (Tasmanian)

The highly decorative hardwood of blackwood outshines almost every other timber in the range of colours it possesses. The heartwood is a rich golden brown through which there may be streaks of reddish brown or almost black. The sapwood is a pale cream-brown, contrasting strongly with the heartwood. Grain is usually straight but sometimes wavy, producing a "fiddle back" figure. Blackwood is rated as moderately decay resistant, though susceptible to insect attack.

Un-patterned, diffuse large pores with narrow rays which can be reddish in colour. 

Australian Blackwood is easily worked with both hand and machine tools but figured wood and pieces with interlocked grain can cause tear-out. Australian Blackwood turns, glues, stains, and finishes well. It also responds well to steam bending. 

Common uses
Veneer, furniture, cabinetry, musical instruments and wood objects.


Certifications Available
PEFC/40-31-26 Promoting Sustainable Forest Management

Dries fairly easily and without undue degrade, although there is some tendency to cupping. 

Working Qualities
The timber works fairly easily but cutting edges must be kept sharpened for end grain working. A reduction of the cutting angle to 20º is usually beneficial in planning and moulding, particularly when the curly grain is present. It can be screwed and nailed well but gluing properties are often variable. It finishes well and takes an excellent stain and polish. 

Fine furniture, shop fitting, cabinets, gun stocks, musical instruments and decorative veneer.
